OEM Nissan Block Parts

Build Power with Block Parts

Investing in quality components today can prevent costly repairs in the future. Trust Nissan Canada to keep your vehicle in top condition. Engine block components include the main casting, cylinder sleeves, core plugs, and oil gallery plugs. These structural parts form the foundation of your engine. Factory block parts use materials designed for specific combustion pressures and temperatures. Quality components prevent oil leaks and maintain structural integrity.

How Block Components Function

Your engine block provides mounting surfaces for all major engine components. Cylinders house pistons that compress air and fuel. Main bearing journals support the crankshaft. Oil galleries distribute lubricant to moving parts. Water jackets surround cylinders for cooling. Core plugs seal casting holes from the manufacturing process. Deck surfaces provide flat mounting for cylinder heads. Nissan engine blocks for vehicles like the 370Z and Titan use specific alloys for strength and heat dissipation. Cylinder walls must maintain precise roundness and surface finish. Oil passages route pressure to bearings and valve train. Timing chain or belt housings integrate with block castings. The block works with complete engines as the central structure.

What Damages Block Components

Core plugs rust through from coolant contamination and allow leaks. Cylinder walls wear from piston ring contact over time. Overheating warps deck surfaces and requires machining. Freeze damage cracks blocks when coolant protection fails. Oil gallery plugs loosen from vibration and create low pressure. Generic aftermarket parts may not seal properly in block ports. Cavitation erodes cylinder walls adjacent to coolant passages. Improper machining during rebuilds creates sealing problems. Broken timing chains punch holes in covers. Extreme overheating can crack main webs. Chemical contamination degrades core plug materials.

Recognizing Block Problems

Replace core plugs when coolant leaks appear at the block sides. Cylinder wear creates excessive oil consumption and low compression. Most engine blocks last 200,000 miles or more with proper maintenance. Overheating events require professional inspection for cracks. Blue smoke from the exhaust indicates cylinder wear. Coolant in oil or oil in coolant suggests serious block or head gasket problems. External oil leaks from gallery plugs need immediate attention. Knocking noises may indicate bearing surface wear. Pressure testing reveals hidden cracks. Genuine Nissan block components include correct thread specifications and proper materials that withstand engine stresses, unlike aftermarket parts that may not fit precisely or use inferior alloys prone to cracking.
